Ok Ive got a treat here. This all comes from a 1998 issue of PC gamer
First off we've got a canceled First Contact game from the dev team MicroProse.
They had previously made a videogame adaptation of star trek generations, which was basically a doom clone with original dialogue and an unlockable alt ending. (There's a path you can take where you never meet Kirk and the enterprise D doesn't get trashed.)
They wanted more leeway to try something different with First Contact, so the plan was to make it a sequel. With the borg queen hiding a copy of herself in the ship computer, taking over some poor scientist and kick starting things off again. Right off the bat the ambition for this game is inspiring, It would have 10 missions, AI companions, deathmatch multiplayer, every cast member with original dialogue, An exploreable enterprise, and we would have seen the enterprise E equivalent of 10 forward.
Alas, all these good ideas and ambition ran out of money, and it never came to be.
Got a little bit of grainy footage, but its pretty lagy and not too interesting.
Second we've got the much more popularly known Secret of Vulcan Fury. I think most of the details here are already well known, but you should get a kick out of it anyway. Ill always wonder how much dialogue they recorded for this before it was canceled.
Here's an extra render
